Based on the results of exploration and in-site test of typical waste dump in southwest mountainous area,the analysis theory and method of waste dump rainfall infiltration are discussed beginning at analysing coal waste's mechanics characteristic and seepage theoty. Fllowed estimating method of waste dump stability is discussed influenced by rainfall. At last a typical engineering example of coal waste dump landslide influenced by rainfall is researched, acquiring research fruit hereinafter.①Particular exploration of typical waste dump in chongqing area and analysis estimate to its area engineering geology are done. Granule gradation、water content、nature density、dry densit etc parameter of waste granular media are tested. The mechanics characteristic of waste are researched by in-site shear experimentation、compressibility experimentation and infiltration experimentation.②The coal waste dumping is different from other consecutive solid material as incompact granule structure. Its shear strength and transforming characteristic also have itself characteristic.
